you can *assign* them but I'm not sure whether or not you can get the rest of the system to work sensibly; that's why I'm not sure about doing this with rtable. reply-to is more likely to be successful since the return route information is attached to the PF state. it's certainly worth a try. sometimes it is just plain not possible to get other people to change their config and it's nice to have ways to deal with it.
